Since the beginning of 2012, we've seen the Arab Spring, the Wisconsin Uprising, the Tar Sands Action, and the ongoing Keystone XL Blockade. In the climate justice movement, some have referred to the recently passed summer as the Climate Summer of Solidarity (SOS).

Speakers at the pre-march rally included the likes of “Gasland” Producer and Director Josh Fox, author and ecologist Sandra Steingraber, environmental journalist and activist Bill McKibben and Food and Water Watch Executive Director Wenonah Hauter; former Pittsburgh City Council member and writer of the ordinance that banned fracking in the city, Doug Shields, as well as members of the Pennsylvania community whose livelihoods have been deeply affected at the hands of the shale gas fracking industry.

Upon the rally's completion, activists zig-zagged up and down Philly's streets, making stops at the Obama for President campaign headquarters and Governor Tom Corbett's campaign headquaters.
